GRAIN-CAR noon. i

Application filedrseptcmber l l, 1922. Serial No. 588,193.

to provide an auxiliary grain car door'to be' employed beneath anyapproved main car door, said auxiliary door adapted to be detachablysecured at its ends to the sides of the door frame and provided with anopening controlled by a closure so that the auxiliary door while inpositionwill permit the flow of grain or other bulk material and bebodily removable when su'flicient' of the materialhas run from the car.

The present invention is designed more especially as an improvement onthe grain car door forming the subjectmatter of an application filed byme March 17 1922, Serial Number 544,501 and has for its prime object toprovide on the auxiliary door, rest means for the main built-on graindoor, said object and others as will appear being attained ina mannerand by means hereinafter fully set forth.

Reference is to be had to the accompanying drawings forming a part ofthis specification, it being understood that the drawings are merelyillustrative of one example of the invention.

Figure 1 is an exterior view of a grain car door embodying my'inventlonshowing the same emplaced;

Figure 2 is a horizontal section on the line 22, Figure 1, showing theauxiliary door in closed and fastened position;

Figure 3 is a view similar to Figure 2 but showing the closure of theauxiliary door swung away from the opening in'said door and showing thesections of the auxiliary door flexed;

Figure 4 is a longitudinal vertical. section taken on the line 4-4,Figure '5;

Figure 5 is a transverse vertical section on the line 5 5, Figure 1.

In. carrying out my invention in accordance with the illustrated examplemy improved auxiliary door designated generally by the numeral 10 has awidth to be disposed in the usual door opening 11 of a car 12 to overlapthe door frame, said auxiliary door being positioned at the bottom ofthe open ing beneath the main door 13 of any approved construction;

Said auxiliary door includes two sections 14 contacting at their opposedends and a closure 15 for the space or opening presented at the junctureof said sections, said closure 15 being hinged as at 15 to one section14 and adapted to overlap the other section when the two sections arealined. The sections 14 at their opposed ends have respectively upperand lower hinge leaves 16 having face members 16 rigid therewith andconnected by hinge pins 17 sothat the door may break or flex outwardlyat the center. y

i In accordance with the present invention I provide on the auxiliarydoor composed of the sections 14 bar sections 20 each having slots 21extending obliquely, there being a pair of such slots in each barsection 20, the slots 21 in a section being opposite to the slotsin theother section. Said slots receive transverse pins 120 passing throughadjacent fixed parts of the auxiliary door sections 14. Knobs 121 serveas handles for sliding the bar sections 20. Said bar sections 20aredisposed on the auxiliary door win the vertical plane of the built-ongrain door 13 and may be moved longitudinally to cause the engagementwiththe pins 120 at the slots 21 to raise or lower the bar sections 20for contacting with the grain door 13 at the lower edge or said sections20 may be so moved as to disengage the grain door 13. The sections 20constitute a rest for the door 13. i

In order to lock the auxiliary door with the sections 14 alined and theclosure 15 swung to the closed position between the said sections, Iprovide a lock bar 22 of a length to extend horizontally across theclosure 15 and overlap the sections 14. Said bar is swingably secured atone end as by a U-bolt 23 which passes through one door section 14 andthrough reinforcing plates 24 applied to said section at the inner andouter surfaces thereof. At the opposite end the lock bar 22 is adaptedto beheld by a latch 25 hinged as at 26 to the opposite door section.The bar 22 is U-shaped or channeled in cross section and accommodates isin the latching position against the bar 22.

\Vith an auxiliary door constructed as describedthe same is placed inposition in the doorway at the bottom. When the grain or other bulkmaterial is to be discharged the lock bar 22 is released'and the'closure15-is swung on its hinge to the open position to permit the material toflow outwardly between the door sections 14. The auxiliary door 10 isremovable bodily, the removal being effected by flexing the door at itshinge 17. Restsections 20 arelowered from engagement with door 13 inremoving auxiliary door 10." v I The auxiliary door 10 is rounded orbevelled at the lower edge as at 10 and at the upper edgeas at 10*, thelower bevel engaging the sill plate 12"* provided on the car 12 of thedoor opening 11' as usual, and the upper bevel being presented to' thelower edge of the main door At the top the closure 15 extends above theauxiliary door 10 and its hinge member 16 to a height tooverlap the maindoor 13% A block 28 is-secured tothe floor of the car 12 just inwardfrom the plane of the auxiliary door 10 at the medial line of saidauxiliary door to constitute a stop' in the placing of the door inposition beneath the main door 13. V

The car is prepared for loading as follows; The auxiliary door-'10 isplaced in position as described andthe bar sections 20 aremoved to theraised position. Then the first ordinary grain door section is placed inposition resting upon the sections 20 and said ordinary grain doorsection 'is then nailed solidly to the doorway post.

Itwill be'observed that the slots 21 are at only a slight angle andmaterially within the angle of repose for which reason there is notendency whatever of the plates-to be moved to alowered position underthe weight ofthe main door 13. v

I would state inconclusion that while the illustrated exampleconstitutes a practical embodiment of my invention, I do not limit'myself strictly to the exact details herein illustrated;- si'nce,manifestly, the same can= be considerably varied without departure fromthe spirit of the invention as definedinthe appended claims.

Having thus described my invention, I claim 1. Anauxiliary grain cardoor adapted to be detachably secured at its ends in a door openingbeneath a main door, said auxiliary door including sections'hingedtogether and presenting an opening therebetwecu, a closure for saidopening hinged to one of said sections and movable to close or openposition, and means on said sections of the auxiliary door movable in avertical plane to engage the maindoor above and constitute a supporttherefor until said main door is nailed in position.

2. An auxiliary grain door adapted to be det'achably secured 1n the dooropening otagrain ca'r beneath'the main door,-said auxiliary door havingmeans to afford. temporary support for the main door,said'means beingmovable on the auxiliary door and into engagement with the main door toconstitute a temporary support thereforuntil said main dooris nailed inposition.

3; An auxiliary grain door adapted to be detachably secured in the dooropening oi. a grain car beneath the main door, and a support for themain door mounted on the auxiliary door, said rest having oblique slotsand the auxiliary doonhaving pinspassing through said slots sothat themovement of saidsupport will serve to-move the same into contact withthe bottom of the main door to hold-said main door temporarily inposition unt i l. nailed.

1. An auxiliary grain car door adapted to-be detachably secured inthedoor opening of the g rainear beneath the main door, said auxiliary doorincluding sections hinged to gether, and an element on-eac'h-section ofthe auxiliary d'oorat the top and movable in avertical plane to'contactwith the main door and constitute a support therefor or to be loweredout of contact 'with the main door, said element each having a pair ofoblique slots therein and the auxiliary door sect-ions havingpinspassing through said slots so that a longitudinal movement of saidelements will impart vertical movement to engage said main door fortemporarily holding said main door until nailed.
